Older HKS cam identification

[Riceburning101]

So I am looking at buying a set of HKS cams from a local guy but they are older and don't have the 264, 272, or 280 stamped. They are HKS stamped so they are legit HKS cams. The part number that is etched on the hex of the cam is M005604 and the other cam is M005704. Supposedly they are 280s let me know what you guys find.

You ran the part number and grind date together.

M005 is the part number,

604 = would be June 2004
704 would be July 2004

So that would make both cams 272 Intake cam

Do both cams have the CAS slot?

Or could one of the M005 be a M006?

M006 would be a 272 Exhaust cam.

A HKS chart is towards the bottom of post 2

Both list 2202-RM005 and that is full part number, looks like HKS uses the base number 2202 for cam for any engine.

Ah sorry your correct M005 and M006 I cleaned and doubled checked because only one does have the CAS slot. So definitely 272s!!!! Awesome appreciate the help. It was the 604 and the 704 that threw me off.
